However, advances in sequencing technologies have improved the state of genomic resources for both wheat and barley. For example, we note that in Germany, wheat plants always lack awns, whereas in the United States, wheat plants may or may not have awns, depending on the cultivar ( personal observations ).

Domestication has genetically not only transformed the brittle rachis, tenacious glume and non-free threshability, but also modified yield and yield components in wheat. The featured traits are plant height, harvest index, lodging, and shattering. It differs from wild wheat in that it has non-shattering spikes, an adaptation that allows the plant to better retain its seeds and to be harvested more easily.
